PINK FUSED ALUMINA (PFA) ABRASIVE

PFA is produced by adding chromium, resulting in increased hardness and toughness. A higher toughness than WFA makes it particularly suitable for production of grinding wheels.

Product code: OM-PF

Description

Pink Fused Alumina belongs to the group of electro-corundum. It is produced by controlled melting of calcined bauxite in an electric arc furnace. Pink fused alumina is iron-free and extremely tough.
